Silver Oxid Nanoparticles Prepared by Pulsed Laser Ablation in Liquid and Thier Study Physical Properties

Abstract

In this work, silver nanoparticles were prepared in a good and distinctive way using the pulsed laser ablation in liquid (PLAL) technique, using an Nd-YAG laser with specific parameters with a wavelength of 1064 nm, an ablation energy of 1000 mJ, a frequency of 1 Hz, and varying the number of pulses by 300, 600, and 900, immersed in deionized water. This research was conducted to study these parameters on AgNP in terms of several measurements. XRD only shows the formation of the pure cubic crystal structure of AgO particles. The development of highly spherical crystals was revealed by subsequent FESEM images (average diameter 60.96 nm, 73.67 nm, and 64.07 nm), respectively. The absorption band of nanoparticles was detected by UV analysis and the wavelength was (404, 405, 410 nm) respectively. The energy gap was (2.39, 2.45, 2.48 eV), respectively. The spherical colloidal Ag-NPs were approved for characterization by FESEM. AgNP were also mixed with 3 g of regular dental filler and the mechanical properties were measured before and after mixing with 2 ml of silver nanoparticles. The results of compressive strength indicated an increase of (17.83%) and the hardness value increased by (5%). This indicates that AgNP have an effect on the mechanical properties and work to increase their efficiency.
